气温变异对唐山市循环系统疾病住院风险的影响
Impact of temperature variability on risk of hospital admissions for circulatory system diseases in Tangshan City
摘要
Abstract
[Background]In the context of global climate change,investigating the impact of temperature variability(TV)on the circulatory system is of significant importance for public health promotion. [Objective]To evaluate the effect of TV on the risk of hospital admissions for circulatory system diseases in Tangshan City. [Methods]Data on hospital admissions for circulatory diseases from four general hospitals in Tangshan between 2021 and 2023 were collected,while concurrent meteorological data were also obtained.A time-stratified case-crossover design was employed to analyze the association between TV and the risk of hospital admissions for circulatory system diseases.Subgroup analyses were further conducted by gender,age,and cold/heat wave days. [Results]A total of 11974 hospital admissions for circulatory system diseases were recorded from 2021 to 2023,with a median daily temperature of 13.90℃.The effects of TV01 through TV07 on hospitalization risks for overall circulatory system diseases and coronary heart disease were all statistically significant(P<0.05).Additionally,the effects of TV01 and TV04 through TV07 on hospitalization risk for stroke were also statistically significant(P<0.05).A 1℃ increase in TV07 was associated with odds ratios(ORs)of 1.041(95％CI:1.032,1.050)for overall circulatory system diseases,1.050(95％CI:1.037,1.064)for coronary heart disease,and 1.029(95％CI:1.014,1.045)for stroke.Furthermore,the effect of TV on the risk of hospital admissions were stronger during cold wave days compared with non-cold/hot wave days. [Conclusion]TV may contribute to increased risk of hospital admissions for circulatory system diseases in Tangshan,and the impact of TV exhibits a certain lag effect.It is suggested to explore and develop targeted intervention mea-sures.关键词
